TANK-VALVE Specification of Letters Patent.

Application filed March 31, 1908.

Patented May 4:, 1909.

Serial No. 424,363.

T 0 all whom it may concern:

Be it known that we, W'ILLIAM M. HAMP- TON and CALEB O. Snrvn, citizens of the United States, residing at Vernon, in the county of Wilbarger and State of Texas, have invented certain new and useful Improvements in Tank-Valves, of which the following is a specification.

The object of the present invention is the provision of an improved valve embodying a novel construction whereby it may be utilized with equal facility either as a tank valve or a trough valve.

The invention further contemplates a valve of this character which is simple and inexpensive in its construction and will always operate in an effective manner to prevent lea rage from the tank or trough when closed.

For a full understandin of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of a valve embodying the invention. Fig. 2 is a side elevation of the same, parts being shown in section.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawing, the numeral 1 designates the tubular base of the valve which has the lower end thereof internally threaded in the usual manner for attachment to the discharge pipe of the tank or trough. The upper end of the base is externally threaded to receive a collar 2 which carries a cage for guiding the valve and limiting the movements thereof. It will also be observed that the upper end of the base is beveled inwardly to form a valve seat 3 designed to co operate with a valve 4 carried by a valve stem 5. The cage comprises three uprights 6 projecting from the collar 2 and connected at their upper ends by a spider 7, an opening being formed at the central portion of the spider through which the valve stem 5 passes. Coo crating with this spider to guide the va ve stem in its movements is a cross bar 8 which extends across the tubular base and is provided with an opening loosely receiving the lower end of the valve stem. The valve 4 is arranged at an intermediate point upon the stem and is preferably integral therewith and the lower edges of the valve are beveled inwardly and carefully ground so that the valve can be accurately seated upon the valve seat in such a manner as to absolutely prevent leakage.

The upper end of the valve stem above the cage is reduced and receives a weight 9 which normally tends to hold the valve upon its seat, the said weight abutting against a shoulder at the base of the reduced end of the valve stem which is indicated at 5 and being held in position by any suitable means such as a key. The upper extremity of the valve stem projects above the weight and when the device is used as a tank valve it is connected to a cable or other member for lifting the valve from its seat when it is desired to open the same. However when the device is employed as a trough valve the upper extremity of the valve stem is connected by a link 10 to one end of a lever 11, an intermediate portion of the lever being pivotally mounted upon an upright standard 12 having the lower end thereof threaded or otherwise detachably connected to an arm 13 projecting laterally from the base. The free end of the lever 11 is shown as perforated for connection with a float of any approved construction. It will thus be apparent that the weight 9 will normally tend to hold the valve upon its seat and that the valve is so constructed as to prevent all leakage, but that by pulling upwardly upon the valve stem either through the medium of the lever 11 or directly the valve can be unseated and the contents of the tank or trough permitted to flow out through the discharge opening.

Having thus described the invention, what is claimed as new is:

1. In a valve of the character described, the combination of a tubular base formed with a valve seat, a cross bar extending across the tubular base, a cage carried by the base, a valve stem guided in its movements by the cage and cross bar and projecting u wardly above the cage, a valve upon tfie valve stem for 006 eration with the valve seat, and a weight 'tted upon the upwardly projecting end of the valve stem for normally holding the valve upon the seat.

2. In a valve of the character described, the combination of a tubular base formed with a valve seat, a cross bar extending across the tubular base, a cage carried by the base, a valve stem guided in its movements by the cage and cross bar and having the up er end thereof reduced, a valve upon the va ve stem for cooperation with the valve seat, and a weight fitted over the reduced *3 end of the valve stem for holding the valve seat, a weight applied to the reduced end of the valve stem for holding the valve normally upon its seat, a standard carried by the base, and a lever pivotally mounted upon the standard and having an operative connection with the valve stem.

In testimony whereof we aflix our signatures in presence of two witnesses.
